CLIP FOR BlCYCLE-SADDLES.

SPECIFICATION forming part of Letters Patent No. 625,873, dated May 30, 1899.

Application filed September 24,1398- fierial No. 691,782. (No model.)

-To aZZ whom it may concern:

citizen of the United States, and a resident of the city of Philadelphia,State of Pennsylvania, have invented certain new and useful Improvements in Tilting-Clips for Bicycle- Saddles, of which the following is a full, clear, and exact description, reference being had to the accompanying'drawings, forming part of this specification.

Myinvention has relation to improvements in clips for securing bicycle-saddles to the saddle posts; and it consists in the construction hereinafter described of an adjustable tilting-clip arranged so that the angle of the saddle may be readily adjusted to any desired degree of inclination by a slight movement of an adjusting-screw so located as to be readily accessible and may be adjusted even while in the act of riding by reaching with one hand beneath the saddle and turning the adjusting-screw.

The proper adjustment and regulation of a bicycle-saddle is, as is .well known to experienced riders, a most important factor in riding a bicycle, and it often occurs in riding,

especially uponroads where occasional hills have to be mounted and descended, that in order toproperly accommodate the rider to the work of the machine the angle of the sad-.

dle should be occasionally shifted, depending upon the fact whether a hill is to be mounted or descended or whether a level road is to be traveled. In mountingahill it is well known that the rear of the saddle should be canted upwardly, so that the inclination of the saddle shall tend to throw the rider forward. In descending this inclination is not desirable, andthe angle of the saddle should therefore be changed so as to slightly depress the rear of the saddle. When ridinguponlevelroads, an intermediate angle is desirable. It is therefore essential to accommodateIthe rider thoroughly to the work before him, especially in hilly country, that the tilting construction should be such that the saddle may be readily canted to the desired angle by a simple adjustment, and it is essentially preferable that the construction shall be such that this adjustment may be accomplished while in the act of riding by simply throwing the weight upon the pedals temporarily and reaching beneath the seat, where the adjusting-screw is readily accessible.

In the accompanying drawings, Figure 1 is a side elevation of a bicycle-saddle having my improved tilting-clip provided thereon and secured to the post-J Fig. 2 is a bottom View of the same with a portion of the clip removed. Fig. 3 isa' sectional view of my improved tilting-clip in connection with the riveting-plate adapted to be riveted to the frame and the securing-eye for securing to the saddle-post, drawn on the lines 3 3, Fig. 1. Fig. 4 is a sectional view of the same construction drawn on the line 4 4 of Fig. 3.

The saddle A may be of any desired construction, to which the member B of the clip is secured by riveting or by any other suitable means. In the construction illustrated the plate 0 is secured to the lower portion of the saddle through the medium of the bolts 0 and the nuts 0, which is a preferable method for securing the same. The slot 0 through which the forward bolt 0 is passed, is preferably elongated, so that the plate may in assembling be adjusted upon the saddle without difficulty and loss of time.

The downwardly-projecting tongue or arm B is rigidly secured to or integral with the se curing-plate B and is pivoted to the section D through the medium of the transverse bolt d. The section D is provided at its lower end with an orifice 0 for the reception of the hori= zontal arm h of the saddle-post, upon which the section D is adapted to fit, lock-nuts 0 being provided in the said lower section, as illustrated in the drawings, for the purpose of clamping the section D upon the seat-post.

Provided upon the section D are perpendicularly-disposed walls 6 e, forming a recess f for the reception of the downwardly-project ing tongue B, which is supported therein pivotally upon the transverse bolt (1, extending through the walls e and through the said tongue B.

A worm-screw F, screw-threaded through out the greater portion of its length, is jour naled in a substantially horizontal position through the lower portion of therecess f in the walls e and has preferably an enlarged milled head f for readily rotating the same, the opposite end being provided with a nut f upon a screw-thread turned thereon to pre vent displacement of the worm-screw,a washer f being preferably interposed between the nutf and the outer surface of the adjacent wall 2 to allow of the free rotation of the wormscrew F Without loosening said nut. Upon the screw-threads of the worm-screw F in the recess f is provided a traveling nut F, of a width slightly less than the distance between the inner surfaces of the walls 6, adapted to travel to and fro upon the worm-screw F, the

nut F being prevented from rotation by the walls 6. The nut F is provided with upweirdly-extending tongue f adapted to fit in a recess 1), provided in the lower portion of the tongue B, formed by the downwardlyprojecting tongues 19, which carry a transversely-disposed pin b fitting in a vertical slot f formed in the upwardlyprojecting tonguef of the nut F.

From the foregoing description it is clear thatwhen the parts are connected and in position upon the seat-post of a bicycle as the worm-screw F is rotated through the medium of the milled diskf the nut F will be traveled in the recess f forward or backward, and the slotted tongue f engaging on the pin b provided on the lower end of the arm B, forces this lower end of the arm in the direction in which the nut F is traveling and will consequently throw the upper end of the said pivoted arm B in the opposite direction and will tilt the saddle in that direction. The saddle may thus be tilted to any desired angle, the

length of the recess f (illustrated in the drawings) being sufficient to provide for any necessary tilting for all ordinary purposes.

may be varied, however, as desired.

In the construction illustrated I have represented the securing-plate B as integral with the downwardly-projecting arm B-and provided with marginal Walls g, adapted to fit snugly around the edges of the plate C, to

which it is riveted at c to better secure the same. This, however, is a matter of detail. The clip may be secured to the saddle in any desired manner.

fore described in detail between the traveling worm-screw and the lower end of the pivoted 7 exactly the same connection in this reverse order and would operate exactly as hereinbefore described. This is too obvious to require illustration or further description. It

is also clear that the details of construction The length of this recess and of the worm-screw F 1 The milled disk f for operating the worm-screWF 1 may be modified and changed without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patcut, is

1. A tilting-clip for bicycle-saddles comprising a supporting-section adapted to be secured to the saddle-post of the machine, a doWnwardly-projecting pivoted arm rigidly secured to the frame of the saddle and pivoted intermediate of its length upon the supporting-section, a rotatable horizontally-disposed worm-screw journaled in said supporting-section carrying a nut upon said screwthreads adapted to travel to and fro in said supporting-section when said worm-screw is rotated, said nut being loosely connected with the lower arm of said pivoted section and adapted to oscillate the same in its backwardand-forward movement to regulate the tilting of the saddle and to hold the same in the desired given position, substantially as described.

2. A tilting-clip for bicycle-saddles comprising a supporting-section adapted to be rigidly secured upon the seat-post of the machine, a movable arm rigidly secured to the frame of the saddle and pivotally connected to said supporting-section, a longitudinallydisposed worm-screw journaled in the walls of the said supporting-section, a nut provided upon said worm-screw adapted to travel to and fro in said recess, upwardly-projecting portion provided upon said nut adapted to a recess in the lower portion of said pivoted arm and transversely-disposed pin provided through said recess in the walls thereof adapted to a slot in said upwardly-projecting portion of said bolt for com municating't-he motion of said pivoted nut to said pivoted arm and to hold it in anygiven position as desired.

3. In a tilting-clip for bicycle-saddles, a section, D, adapted to be rigidly secured upon the saddle post, upwardly-extending walls, 6, e forming a recess, f, a longitudinally-disposed worm-screw, F, journaled in the walls, 0. provided with an enlarged head for rotating said bolt, a pivotal section secured to the frame of the saddle havingadownwardly-pro- I jecting arm, B, pivotally secured in said re- It is clear that the connections hereinbecess upon the transverse bolt, d, said arm, B, being provided with a recess, 1), traveling nut, F, provided upon the screw-threads of said worm-screw, F, prevented from rotation by the walls, 6, u pwardly-extendin g slotted tongue, f", provided upon said nut, F, adapted to project within the recess, 1), transversely-dis posed pin, 17 provided through said recess, 1), secured in the walls thereof and engaging in said slot, substantially as described.

In witness whereof I have hereunto set my hand this 22d day of September, A. D. 1898.
